wp_list_pluck() WP 1.0

Pluck a certain field out of each object in a list.

This has the same functionality and prototype of array_column() (PHP 5.5) but also supports objects.


Array. Array of found values. If $index_key is set, an array of found values with keys corresponding to $index_key. If $index_key is null, array keys from the original $list will be preserved in the results.

Works based on: WP_List_Util()
1 time = 0.00001s = speed of light | 50000 times = 0.45s = very fast

No Hooks.

$list(array) (required)
